Specification of Letters Patent.

Patented May 5, 1908.

Application filed November 16, 1907. Serial No. 402,485.

To all whom it may concern:

Be it known that I, JOHN T. TOLANI), a citizen of the United States,residing at Atwater, in the county of Kandiyohi, State of Minnesota,have invented certain new and useful Improvements in Attachments forSulkies and Gang-Plows and I do hereby declare the following to be afull, clear, and eX- act description of the invention, such as willenable others skilled in-the art to which it appertains to make and usethe same.

This invention relates to new and useful improvements in plows and ithas more particular reference to a stone dodging attachment for gang orsulky plows, the object being to provide a novel construction,combination and arrangement of parts.

The details of the invention will appear in the course of the followingdescription, in which reference is had to the accompanying drawings,forming a part of this specification, like characters of referencedesignating similar parts, throughout the several views, wherein Figure1 is a side elevation of a plow constructed in accordance with thepresent invention. Fig. 2 is a top Fig. 3 is a detailed view anunlocking device for the lever comprehended in the invention. Fig. 4 isa detailed sectional view showing a connection between the frame and asupporting standard.

The invention is shown as applied to a plow of the Deere sulky gangtype. This particular type of plow, as is well known, includes a framedesignated by the numeral 5, plow beams 6 carrying at their rear endsthe plows 7, front and rear crank hangers 8 and 9 for the beams 6, thehangers 8 and 9 being adjustably connected by suitable conventionallever operated means with the frame 5, depending bracket bearings 10 forthe offset ends of the hangers 8 and 9, a land Wheel 11 mounted upon thecrank arm 12 of a stub axle 13, journaled in one of the side bars of theframe 5, a furrow wheel 14 and a stand ard 15 which carries the furrowwheel and which passes through a sleeve 16 mounted at the front end andat one side of the frame 5. Pivuted to a bracket 17 mounted rigidly uponthe standard 15, is a lever 17 having plan view thereof. 4

F connection with the frame 5, by means of a lug 18. These elements areall well known in connection with a sulky plow of the above specifictype and are herein illustrated to show the application of theattachment embodying the present invention.

The lever 17 is utilized as a salient element of the invention and inpractice has its pawl 19 held from engagement with the rack 20 by a ring21 surrounding the upper end of said lever and embracing the handle ofthe pawl. At the upper end of the lever 17 a snap hook 22 is provlded,which is designed for engagement in selected links of a chain 23, thelower end of which is connected to the adjacent side bar of the frame 5.The chain 23 is of a length sufficient to allow of the lever 17 beingmoved to its fullest extent.

Projecting laterally from the upper end of the standard 15, is an arm24, to which the tongue is secured. A retractile coil spring is securedto one end of the arm 24 and at its other end is connected to a chain26. Midway of the lever 7 a snap hook 27 is provided, which is designedfor connection with a selected link of the chain 26.

In use, when any one of the plows 7 strikes a stone, the lever 17 beingresiliently suspended, the plows and beams will rise and ride over thestone, the lever 17 having downward movement against the tension of thespring 25. As soon as stone is passed, the spring 25 raises the lever 17to its upward limit as controlled by the chain 26, whereby the plows 7will be forced into the ground. Thus, the stone dodging operation isautomatic and no ground is left unplowed, except that taken up by thestone.

The frame is set at selected positions with relation to the standard 15,by raising or lowering the lever 17, this action being attained bytaking up and letting out the respective chains 23 and 26 as will bereadily understood.

What is claimed is:

A plow of the type set forth, comprising in combination with a frame,plows supported therefrom, a hand lever for raising and lowering saidframe and plows and means for holding said hand lever at selectedositions, a chain connected to said frame an adjustably to said handlever at one side thereof for In testimony whereof, I afliX mysignature, limiting the upward1 movement thereof, a in presence of twowitnesses. ton ue su ortin e ement, a s rin connec%ed to s fd elen lentand a ohain eonllected JOHN TOLAND 5 to said s ring and adjustably tosaid hand Witnesses:
